The Pirahã language is of great interest to linguists, but only a few people apart from the Pirahã tribe are fluent in it. Keren Everett's former husband Daniel Everett, whom she married in 1969, is the best-known authority on the language. He acknowledges his ex-wife as an expert on the prosody of Pirahã. They lived among the Pirahã from 1978 to 1983 and from 1999 to 2002. Following their separation in 2005, Keren returned to Brazil where, as of 2007, she was continuing her missionary work among the Pirahã.
